From 3570869c9ae2c4df14b15423789919e514322916 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc=20Andr=C3=A9=20Tanner?= Date: Wed, 7 Dec 2016 16:49:29 +0100 Subject: Move all lua related files to lua/ subfolder Also remove the lexers sub directory from the Lua search path. As a result we attempt to open fewer files during startup: $ strace -e open -o log ./vis +q config.h && wc -l log In order to avoid having to modifiy all lexers which `require('lexer')` we instead place a symlink in the top level directory. $ ./configure --disable-lua $ rm -rf lua Should result in a source tree with most lua specifc functionality removed. --- lua/lexers/glsl.lua | 132 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 132 insertions(+) create mode 100644 lua/lexers/glsl.lua (limited to 'lua/lexers/glsl.lua') diff --git a/lua/lexers/glsl.lua b/lua/lexers/glsl.lua new file mode 100644 index 0000000..6d59da8 --- /dev/null +++ b/lua/lexers/glsl.lua @@ -0,0 +1,132 @@ +-- Copyright 2006-2016 Mitchell mitchell.att.foicica.com.
